Symptoms of novel coronavirus pneumonia are non-specific, with fever, dry cough, and malaise as the main symptoms in the early stages, and in some patients, loss of smell and taste as the first symptoms. Some patients may have no clinical manifestations at the beginning of the infection, and only later develop clinical manifestations, i.e., they are in the incubation period of “asymptomatic infection”. Therefore, it is important to continuously monitor your health, and if you have suspicious symptoms, such as runny nose, sneezing, cough, nasal congestion, loss of smell and taste, dry cough, or fatigue, and if you have been to a high-risk area or have been in contact with a patient with fever, you should go to a hospital fever clinic for a novel coronavirus nucleic acid test. We recommend that you actively get vaccinated against the new coronavirus and insist on self-protection by insisting on wearing a mask, maintaining social distance, paying attention to personal hygiene, and keeping indoor ventilation. Try to avoid activities in places where crowds gather, spaces are confined and ventilation is poor.
